Global Oil and Gas Stocks: Anomalies, Systematic Risks and Mispricing

International Journal of Finance &Economics, EarlyView.
ABSTRACT We analyse anomaly and factor risk premia in the global oil and gas (OG) sector, which plays a central role in the global economy through its importance for energy supply, industrial production, and capital markets. Using firm‐level and portfolio data, we examine whether cross‐sectional return patterns reflect systematic risk compensation or ...
